Three, utility model content
The purpose of this utility model is to design a kind ofly demonstrates the instruments used for education that chemical fountain experiment is used, so that experimental implementation step is simplified is quick, visual phenomenon is lively, during experiment, success ratio is high, and experimentation is safe and reliable, energy-conserving and environment-protective.
The utility model solves the technical scheme that its technical matters adopts: a kind of optimization device of chemical fountain experiment, by iron stand (1), conical flask (2), rubber stopper (3a, 3b, 3c), separating funnel (4), Y tube (5), iron clamp (6), flask (7), sharp nozzle canula (8), conduit (9a, 9b, 9c), tongs (10) and container (11) form, conical flask (2) is placed on iron stand (1) base, separating funnel (4) is connected with conical flask (2) by rubber stopper (3a) with conduit (9b), flask (7) is fixed on the pillar of iron stand (1) by iron clamp (6), sharp nozzle canula (8) is connected with flask (7) by rubber stopper (3b) with conduit (9a), container (12) is connected with rubber stopper (3c) with conduit (9c), sharp nozzle canula (8) and conduit (9b, 9c), by Y tube (5) series connection, between separating funnel (4) neck and stopper, have respective slot or aperture, container (12) neck below is provided with a breeder tube (11), conduit (9a, 9b, 9c) and on sharp nozzle canula (8), be all connected with one section of flexible rubber hose, flexible rubber hose can be proofed sleeve or emulsion tube, is convenient to the use of tongs.
The beneficial effects of the utility model are by together with the device organic combination of gas generation device, sump assemblies and demonstration fountain experiment, simplified experimental procedure, save the operating process of removable parts equipment, stopped the gas leakage that a plurality of links cause, both improve work efficiency, guaranteed again the success of fountain experiment.Experimental phenomena is analysed clearly, is convenient to observe, and handling safety is reliable, energy-conserving and environment-protective.
Four, accompanying drawing explanation
Below in conjunction with drawings and Examples, further illustrate structure and characteristics of the present utility model, in accompanying drawing:
Accompanying drawing is a kind of optimization device structural representation of chemical fountain experiment
In figure 1. iron stand 2. conical flask 3. rubber stoppers (3a, 3b, 3c) 4. separating funnel 5.Y shape manage 10. tongs 12. containers of 6. iron clamp 7. flask 8. sharp nozzle canula 9. conduits (9a, 9b, 9c).
Five, embodiment
Below in conjunction with accompanying drawing, with specific embodiment, the utility model is further described, referring to accompanying drawing:
In accompanying drawing illustrated embodiment, be provided with iron stand (1), conical flask (2), rubber stopper (3a, 3b, 3c), separating funnel (4), Y tube (5), iron clamp (6), flask (7), sharp nozzle canula (8), conduit (9a, 9b, 9c), tongs (10) and container (12).
Implement the utility model, first conical flask (2) is placed on iron stand (1) base, separating funnel (4) is connected with conical flask (2) by rubber stopper (3a) with conduit (9b), flask (7) is fixed on the pillar of iron stand (1) by iron clamp (6) after standing upside down, sharp nozzle canula (8) is connected with flask (7) by rubber stopper (3b) with conduit (9a), container (12) is connected with rubber stopper (3c) with conduit (9c), and sharp nozzle canula (8) and conduit (9b, 9c) are in series by Y tube (5).
Implement the utility model, on described conduit (9a, 9b, 9c) and sharp nozzle canula (8), be all connected with one section of proofed sleeve or emulsion tube, so that the use of tongs.
Implement the utility model, its neck below of described container (12) has a breeder tube (11), and container (12) is made with transparent material.
Implement the utility model, as take laboratory and prepare ammonia and verify that the experiment of the character that ammonia is very easily water-soluble is example, during experiment, first sodium hydrate solid is added in the conical flask (2) of gas making device, the rubber stopper (3a) that separating funnel (4) and conduit (9b) are housed is filled on conical flask (2), pour appropriate strong aqua into separating funnel (4) is inner, then in the container (12) of storage liquid, add the water that drips phenolphthalein indicator, liquid level is no more than the aperture (11) on container, then sharp nozzle canula (8) and conduit (9a) are contained on rubber stopper (3b) and are connected with flask (7), and flask (7) is upside down in iron clamp and is fixed on iron stand (1) after clamping, conical flask (2), flask (7) has flexible rubber hose to be connected with Y tube (5) with the conduit on container (12).Tongs in closure catheter for closing (9c) and open conduit (9a, after tongs 9b), open again the piston of separating funnel in gas making device (4), after strong aqua drips, contact with solid sodium hydroxide and have ammonia to overflow, with moistening litmus red test paper, be placed on the export inspection of conduit (9a) a little while, if discovery change indigo plant shows the ammonia in flask and has collected full, at this moment closure catheter for closing (9a, tongs 9b), open the tongs on conduit (9c), the aperture (11) press...withing one's finger on sump assemblies container (12), another is held crowded container (12), container (12) rises to flask (7) because being out of shape rear liquid with conduit (9c), once the inner sharp nozzle canula (8) of flask (7) has water out to decontrol immediately both hands, at this moment the liquid that can observe in container continues ejection at sharp nozzle canula (8) mouthful, form beautiful fountain, liquid becomes bright-coloured redness in flask.
